براغي ماكينة 5/16-18 × 1-3/4 بوصة | رأس مستدير مشقوق | فولاذ عادي (200/عبوة)

I needed some sturdy fasteners for a workbench assembly and these machine screws were perfect—the 1-3/4 inch length gave just enough grip for thick wood. The slotted drive was easy to tighten with a standard screwdriver, no stripping issues at all.

These screws are a bit tricky to turn with a regular screwdriver because of the slotted head, but once you get them in, they hold tight and haven't stripped on me. The plain steel finish looks exactly like what I needed for my workbench project. Exactly what you'd expect for a solid indoor fastener.

I needed a bunch of 5/16-18 machine screws for a wooden jig I'm building, and these 1-3/4" round heads are exactly the right length and grip. The slotted drive takes a flathead screwdriver fine, though I wish they had a Phillips option for faster driving with a drill.
